Hi Daniela,Are you absolutely sure that in your case the -pbc nojump option CAUSES the rotation? Or could it be that your molecule is rotated a bit, and due to a too large difference between the reference and the starting frame, this causes weird results (I've had that, but that was definitely my m

Hi,Do note how the jumps are removed. First of all, this is done atom-wise. For the first frame, the position of each atom is checked against the position in the given reference, and if there's a distance between them larger than half the box vector, it is shifted back over the lattice. For each su
